3 Claims. (Cl. 4-213) i Thisinvention relates to ventilated toilet bowls, 1 the Vprimaryobject of the invention being to provide means for circulating air through'thetoilet bowll creating a' suction therein, the means for creating suction being controlled by a weight on the bowl seat. i y j l An important object of the Vinvention is to provide an electric fan operated by a circuit controlled by the movements of the cover of the seat,

to the endthat the circuit to the motor will re- 1 claims, it being understood that changes may be l made in the construction and arrangement of parts without departing from the spirit of the invention as claimed. l

Referring to the drawings: A

Figure 1 is a fragmental plan view of a closet bowl equipped with a seat and cover constructed in accordance with the invention.

Fig. 2 is a vertical sectional view through the rear end of the closet bowl and hinge support for the seat and cover.

Fig. 3 is an enlarged elevational view partly broken away illustrating the position of the mercury switch used in the circuit, when the cover is swung to its closed position.

Fig. 4 is a similar elevational view of the supporting hinge of the device illustrating the position of the mercury switch when the cover is in its open position.

Fig. 5 is a similar elevational view of the hinge structure illustrating the circuit as completed through the mercury switch when pressure is directed to the operating lever, the cover being open.

Fig..6 is a sectional view taken on the line 6 5 of Fig. 3.

Referring to the drawings in detail, the reference character 5 indicates the conventional toilet bowl with which the attachment is used. The device forming the subject matter of the invention comprises the suction intake member which is in the form of a housing '6 formed with a reduced forward end l, which is open to the space directly between the seat 3 and top or upper edge 9 of the bowl 5.

Communicating with one end of the intake member 6 is `the pipe I0 that communicates with the suction fan housing II in which the suction fan I2 operates, the suction fan housing being also inl communication with a discharge pipe, not shown, through which air is directed. Therear end of the seat 8 is mounted upon hinge members pivoting on hinge pin I5 for vertical movement with respect to the bowl 5 and is heldin its elevated position under normal conditions, by means of the coiled spring I3 which is shown as seatedin a recess in the lower surface of the seat, the spring resting on the upper edge of the bowl. Pivotally connectedv with the hinge member IB at one side of the hinge,`is the arm I'I, which arm has pivotal connection with the arm I8, that in turn is securedto oneend ofthe shaft I9, which shaft operates in a bearing opening formed in one end wall of the suction intake member 6. Mounted withinvthe suction intake member E and secured tothe inner end of the shaft I9, is the arm 20 on which the plate 2I is pivotally mounted, the plate 2| having the clip 22 mounted thereon,

lwhichclip grips. themercury switch 23 securing the switchin position. The mercury switch carriescontacts in one end thereof, and these contacts connect with the wires 24 that in turn provide a circuit between the mercury switch and ymotor 25 of the fan I2. The position of the arm 2li with respect to the shaft I9 is such that when the arm 20 is moved, due to slight frictional contact between the plate and arm, the plate will swing upwardly to the position as shown by Fig. 4, when the cover I4 is moved upwardly to the dotted line position; The position of the plate 2| shown by Fig. 4, is the limit of the movement of this plate when operated by the cover and arm Il. When the mercury switch is in this position, the contact points of the mercury switch are free and the circuit through the wires 24 is broken.

The reference character 2B indicates an oper- Y ating arm pivotally connected with the wall of the member 6, the end 21 of the arm 2B being rounded and disposed directly under the rear edge of the seat 3. The opposite end of the arm 26 connects with the switch actuating arm 28 which is constructed to t over the shaft I9, as clearly shown by Fig. 4 of the drawings. It follows that when pressure is directed to the rear of the seat 8, the,

. toilet bowl, the suction drawingA 01T air through the pipe l and discharging the air to the atmosphere.

Having thus described the invention, what is claimed is:

1. The combination with the hinged seat. cover of a toilet bowl, of a Ventilating attachment comprising a suction intake housing having an open side communicating with the spacey between the seat and upper edge of the bowl, a suction pipe connected with the intakehousing. a motor operated suction fan operating within` the pipe adapted to draw-gases from the bowlx a wiring system providing an electric circuit between the ran motor and source of electricity supiy,v a mercury switch in, the wiring circuit mounted within the housing, a switch operating arm,y an arm connecting the switch operating. arm and cover, adapted to partially operate the switch upon movement of the cover to its open position. a nivoted arm extending'into the housing, the outer end ofY the pivotedarm engaging the lower surface of said seat. an arm extending upwardly from the inner end of said .pivoted arm and operated by downward movement or .the seat. further operating said switch and completing the circuit to. the ian motor.

2. The. combination. with the hinged seat and cover of a toilet bowl, of a Ventilating attachment comprising a suction intake. housing having an onenr side. communicating with space between the Seat and upper edge of the bowl, a suction pipe connected with the intake housing. a motor operated suction fan operating within the pipe adapted to draw gases from the bowl, a wiring system providing an electric circuit between the fan motor and source of electricity supply, a mercury switch in the circuit pivotally mounted within the housing adapted to complete the circuit to the fan upon upward movement of the cover, an arm connected with the cover, means for transmitting movement of said seat cover through said arm, to said mercury switch partially tilting said switch, an operating 'arm eX- tending into the housing with one end engaging the seat and a switch actuating arm mounted on the other end of the operating arm and engaging said switch and moving the switch to its limit to complete the circuit to the fan when pressure `is directed to the seat and operating arm.

3. The combination with the hinged seat and cover of a toilet bowl, of a Ventilating attachment comprising a suction intake housing having an open side communicating with the space between the seat-and upperiedge of the bowl, a suction pipe connected with the intake housing in communication therewith, a motor operated suction fan operating within the pipe and adapted to draw gases from the bowl, a wiring system providing an electric circuit between the fan motor and a source of electricity supply, a mercury switch in the circuit mounted inthe housing, an operating arm operated by downward pressure on thertoilet seat and connected to a switch actuating arm for raising said switch actuating arm,

and mean-s controlled by the movement of the cover of the seat to its open position for moving said switch into thev path of travel of said switch vactuating arm.
